ImageIcon无法与我一起使用 [英] ImageIcon does not work with me

问题描述

我编写了非常简单的代码来显示葡萄的图标，但是代码仍然没有显示任何内容

i wrote very simple code to display an icon of the grapes but still the code doesn't show me anything

这是我的代码

import javax.swing.*;
import java.awt.*;

public class Code {
ImageIcon ii = new ImageIcon("image/grapes2.jpg");
JLabel label = new JLabel("Grapes", ii, SwingConstants.CENTER);
JFrame frame = new JFrame("ImageIcon");

public void ui(){
    label.setHorizontalTextPosition(SwingConstants.CENTER);
    label.setVerticalTextPosition(SwingConstants.BOTTOM);
    label.setIconTextGap(5);

    label.setOpaque(true);
    label.setBackground(Color.GRAY);

    frame.setSize(2300,2300);
    frame.setVisible(true);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.add(label);

}

}

推荐答案

如果即使在最终致电frame.setVisible(true)之后仍然看不到图像图标，那么请查看我在同一上下文中被问到的其他帖子.

If image icon is not visible even after calling frame.setVisible(true) in the end then have a look at my another posts that is asked in the same context.

• 如何从项目文件夹中检索图像?

  从另一个目录读取图像

  尝试

  // Read from src/image folder
  ii = new ImageIcon(ImageIO.read(getClass().getResource("/image/grapes2.jpg")));
  label.setIcon(ii);

  值得阅读如何使用图标以及此处是直接从那里得到的样品.

  It's worth reading How to Use Icons and here is the sample directly from there.

  ImageIcon icon = createImageIcon("images/middle.gif",
                               "a pretty but meaningless splat");
  label1 = new JLabel("Image and Text", icon, JLabel.CENTER);
  ...
  label3 = new JLabel(icon);
  
  /** Returns an ImageIcon, or null if the path was invalid. */
  protected ImageIcon createImageIcon(String path,
                                             String description) {
      java.net.URL imgURL = getClass().getResource(path);
      if (imgURL != null) {
          return new ImageIcon(imgURL, description);
      } else {
          System.err.println("Couldn't find file: " + path);
          return null;
      }
  }
  

  了解更多信息使用getResource加载图像，其中视觉上解释它.

  Read more Loading Images Using getResource where it is explained visually.

  例如名为omega的目录中的类文件. omega/images目录中的图片.

  For e.g. Class file in directory named omega. Image in omega/images directory.
